SELF-DUMPING SCCWV.

Application filed November 4, 1924. Serial No. 747,356.

To all whom it may concern Be it known that I, Pnrmr VINCENT, a

citizen of the United States. and a resident of Olympia, in the county of Thurston and State of ashington, have invented certain new and useful Improvements in Self- Dumping Scows, of which the following is a specification.

My present invention relates generally to scows, and my object is the provision of a scow so constructed and adapted to be operated as to form an effective self-dumping arrangement which will obviate the usual cost and delays in unloading, especially the R dumping of garbage and filling materials which are to be unloaded in the water.

In the accompanying drawings which illustrate my present invention and form a part of this specification, 1

Figure 1 is a partial side view of a scow constructed in accordance with my invention,

Figure 2 is a partial longitudinal section therethrough,

Figure 3 is a vertical transverse section taken therethrough, and

Figure 4 is a partial top plan View thereof.

Referring now to these figures my invcntion proposes a scow including a reversible hull, the opposed decks and 11 of which form the top and bottom depending upon which way the reversible hull is turned. These decks 10 and 11 are spaced apart by the hull sides 12 and also bya longitudinally central partition wall 13, the latter of which divides the entire hull into separate side compartments 14 and 15. Each of these compartments 14 and 15 has a false bottom, the bottom 16 of the compartment 14 being adjacent to the deck 11 and the bottom 17 of the compartment 15 being adjacent to the deck 10, these false compartments forming between the same and the decks adjacent to which they extend, air spaces 18 and 19. The compartments 14 and 15 are water compartments and it is contemplated'that the partition wall 13 and the false bottoms 16 and 17 will be caulked like the hull sides 12 so that there will be 30 nointercommunication between the cornpartments 14 and 15 or between these air compartments and the air chambers 18 and 19. Where there is any leakage of water into the air chambers 18 and 19, this may be displaced through normally closed drain pipes 20 communicating with these chambers through the hull sides 12.

Opening through thelrull sides: 12 into each of the water chambers 14 and 15 are water inlet and outlet openings normally closed by outwardly opening valves 21, each of these valves adapted to be opened by a particu 27, the latter of which are hinged at their lower ends as at 28 to the decks so that these bulwarks are free to fold inwardly against the deck as indicated in the lower portion of Figure 3 when the latter is turn downwardly.

It is also to be noted that the water inlet and outlet valve 21 of each water chamber is located immediately adjacent to the false bottom of that chamber and that each water chamber has a valved air outlet 29 opening through its false bottom and through the deck adjacent to which its false bottom is mounted, the false bottom of each of the water chambers 14 and 15 being disposedtherein at a point above the water line of the hull when the scow is unloaded.

In Figure 3 I have shown the hull of the scow deep in the water as it will appear when loaded, the deck 10 being uppermost with the load thereon between the upstanding bulwarks 26. To cause the scow to dump, as-

suming at this time that both of the water.

chambers 14 and 15 are free of water, the handle 23 of the rod 22 controlling the water inlet and outlet Valve 21'of the water chamber 15, is actua zd to open said valve 21 so that water is free to .enter the chamber 15,

overturning the water inlet and-outlet valve remains open and it is obvious that as the load is dumped the hull rises in the overturned position with the deck 11 uppermost, the water line being then below the falsev bottom 17 of water chamber 15 so that the water previously filling the chamber is allowed to run out of the same until it is entirely clear, when the valve is closed and the scow is again in position for they reception of a loadupon its deck 11.-

It is obvious from this that with the scow constructed as shown in Figure 3 it is always overturned to the right and for uicker action in large scows it is obvious t at a plurality of valved water inlet and outlet ports may be provided instead. of but one for each water chamber as shown.

It is obvious that other refinements may be made and that in order to' relieve in part the strain upon the hinges 28' of the stanchions 27, the upper ends of these stanchions may be connected by cables, chains or other flexible connections 30 with the deck' stringers 25 as shown in Figures 3 and 4.

Thus it is obvious that by providing a scow having a hull constructed, as shown with lengthwise water-tight bulkheads at respectively opposite sides and adjacent to its opposite decks, with the bottom of each bulkhead above the normal water line of the hull when the scow is unloaded, and to-- gether with means for opening the side inlet valves from the opposite si e of the hull with respect to such valve, it follows that i the dumping of the scow may be accom'- plished with ease and facility, in such manner as to avoid the slow and more expensive now in use.

methods of discharging the load that are 'I claim:

side walls and a central longitudinal parti-v tion wall connecting said decks and forming longitudinal side compartments, each of said compartments having a false bottom, one

adjacent to one of the said decks and the other adjacent to the other deck, bulwarks inlet and outlet through its outer side wall located'adjacent to its false bottom, and

each. of said compartments having valved air emape means extending through its false bottom and through the adjacent deck, for

the purpose described. 2. A self-dumping scow including a hull having a pair of oppositely facing decks,

side walls and a central longitudinal partition wall connecting said decks and forming longitudinalcside compartments, each of said compartments having a false bottom, one adjacent to one of the said decks and the other adjacent'to the other deck,

bulwarks hinged to the side of the decks to foldinwardly therealong, each of the said longitudinal compartments having a valved deck, the said hull having oppositely curved ends and the said falsebottoms of the con1-- partments forming between the same and the adjacent decks air spaces provided with drain plugs for the purpose described.

3. A self-dumping scow'including a. hull having two decks opposite one another and a central longitudinal partition wall dividing the same into similar side compartments,

0! located adjacent each compartment bein to one of the decks and having a false bot.- tom spaced from the other deck, and each compartment having a valved water inlet and outlet port located in the outer side wall thereof adjacent-to its said false bottom.
